NAIL BOX non NAIIlING ivmcnrnns.

Application filed December 12, 1925', Serial No. 75,090, and 'in FranceDecember 12, 1924.

The present invention relates to an improved nail box fornailingmachines.

v The special features of the said invention consist in the -meansemployed for guiding the nails; in the means for obviating all gripping;and in the improvedconstruction I of the apparatus whereby its rigiditywill be assured and its practical operation will be afforded.

In the appended drawings: 7 r

Fig. 1 is an elevation view of the apparatus in full size) viewed fromthe right hand side, showing its closing plate.

Fig. 2 is an analogousfront view.

Fig. 3 is a corresponding view from the right hand side, with theclosing plate removed, thus showing the internal elements.

Fig. 4 is a bottom plan view of the apparatus.

Fig. 5 is an internal view of the left hand guide for the nails which isso mounted as to have straight line movement.

Fig. 6 is an internal view of the right hand jaw-guide which is pivotedon its supporting 25 axle.

Fig. 7 is a like view of the left-hand die.

Fig. 8 is an interior view of the right hand. die. The box comprises ametallic body 1 having a guide 2 upon its upper end, and in which thedriving plunger 2 operates. The body is provided with recesses 3 .and atapped boss 4, and it is through the medium of these elements that thebody is supported upon the machine. An inclined feed passage 5 is formedin the body 1 for thepassage of nails, and it is through this passagethat the nails are introduced to be driven by the plunger 2.

The nail guiding bar 6 is mounted in the recess 7 formed in one face ofthe body 1, said bar having its upper end provided with a slot 8slidably engaged upon the bolt 9 carried by said body, said bar beingurged inwardly by a coil spring 10 associated with a plunger 11, therebeing a stud 12 which guides said spring. A second guide bar 14 ispivotally mounted in the recess upon the stud 15, the bars 6 and 14having their opposed faces provided with longitudinal grooves 16 and 17,respectively, which when confronting provide a passage for the nails fedthereto through the passage 5.

Slidable in the recess 18 formed in th elongated base 18 of the body areopposed dies 19, retained and guided by cross pins 19 .slidable in theslots 20 formed in said dies. as clearly shown in Figure3 of thedrawing. The inner or abutting ends of the dies 19 are provided withshoulders 21 and with which the lower ends ofthe respective bars 6 and14 engage for interlocking-err gagement. To yieldably hold the dies 19in contacting. relation springs 21 are provided and are retained inplace by the caps 22.

Cap screws 23 are provided and engage the threaded openings 23' formedin the body and serve to retain the cover plate 24 in position to closethe recessf7 The adjacent ends of the dies are provided with beveledfaces 24, which serve to guide the nails as they are successively actedupon by the driving plunger 2. It will be obvious that as the nails arefed between the bars 6 and 14, the former will slide while the latterwill swing in order that nails of various sizes can be driven. It willbe of course understood that upon movement of the bars the dies will beslid outwardly due to the interlocking connection between the lower endsof said bars and the shoulders 21 0f the dies. The plunger 2 hasmovement sufficient to follow a nail as it is driven through the opening25in the base 18.

I claim:

1. A nail box for nailing machines, comprising a body having a recess inone face thereof, a pair of laterally movable nail guiding bars mountedin the recess, said body having a passage therein for feeding nailsbetween the bars, nail engaging dies slidably and yieldably associatedwith the body for engaging the nails to hold the same indriving-position, said dies being interlocked and movable with the bars.

, 2. A nail box for nailing machines, comprising a body, a pair of nailengaging bars -mounted therein, one bar having a straight line movementand thepther a pivotal movement, said body having an inclined nailfeeding passage for feedlng nails between and springs carried by thebody and engaged with the dies for normally urging said dies towardseach other.
